IPv4 and IPv6 dual stack brocken sind at least 1075

Hi,

 

It seems that runing snomONE on a system with both IPv4 and IPv6 address is broken. I'm no sure since when, I seem to remember that it worked in the first 4.5 version.

With 1075 and 1090 the log file goes crazy with this:

[0] 2012/09/13 11:00:49:	TCP(IPv4):Could not bind socket to port 443 on IP 0.0.0.0
[0] 2012/09/13 11:00:49:	FATAL: Could not open TCP port 443 for HTTP/HTTPS
[0] 2012/09/13 11:00:49:	(IPv6)Could not bind socket to port 443 on IP [::]
[0] 2012/09/13 11:00:49:	FATAL: Could not open TCP port 443 for HTTP/HTTPS
[0] 2012/09/13 11:00:49:	TCP(IPv4):Could not bind socket to port 389 on IP 0.0.0.0
[0] 2012/09/13 11:00:49:	FATAL: Could not open TCP port 389 for HTTP/HTTPS
[0] 2012/09/13 11:00:49:	(IPv6)Could not bind socket to port 389 on IP [::]
[0] 2012/09/13 11:00:49:	FATAL: Could not open TCP port 389 for HTTP/HTTPS
[0] 2012/09/13 11:00:59:	(IPv6)Could not bind socket to port 80 on IP [::]

 

It repeats over and over, connections to the webinterface are intermittend (since it shuts down port 80 and 443 and restarts them all the time).

This also kills auto-provisioning. The only ports that seem to work reliably are 5060 and 5061 (SIP and RTP).

This error will occur if the ports are being used by another service. That other service could previous instance of the snomONE PBX too.

Under Linux systems, OS does not release the ports up to a minute after the process has exited.

We dont link statically. There are some issues with binding to "all addresses", in order to make IPv6 migration easier some OS also bind to IPv6 addresses. We tell the OS no to do so, but maybe something really is different in the library that screws it up. Anyway, the /proc interface has a settings for that (/proc/sys/net/ipv6/bindv6only), you can try to put a "1" into that and then the PBX should always bind only to the IPv4 and Ipv6 interface seperately.
